Letter D would not be a quadratic.
x^2 + 3x - 2 = x^2 - 2x once simplified becomes
5x - 2 = 0 this is linear.
Bigger fraction. Imagine 2/10 and 2/5. 2/5 would be much bigger, since the denominator is smaller, showing a bigger number.

Answer:
h = 8 sqrt(2)
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 45 = 8 / h
h sin 45 = 8
h = 8 / sin 45
h = 8 / (1 sqrt(2)
h = 8 sqrt(2)
If a triangle has side lengths of 5.6 yards, 7.1 yards, and
x yards, then the range of possible values of x would be 1.5 < x <
12.7. The correct answer between all the choices given is the
first choice or letter A. I am hoping that this answer has satisfied your query
about and it will be able to help you.
